How many categories/forums/subforums can one vBulletin install support?
 

I'm starting a forum that will have many cities, with each city having the same 50 subforums. Is there a limit to how many forums/subforums I can create, or is it a matter of ease of maintenance? If it's the latter, is there a way to better manage the list of forums/subforums in the Forum Manager since the list will become quite cumbersome in no time? Thanks.
